A clinical trial of Exluton a progestogen only contraceptive pill containing 0.5mg lynestrenol amongst lactating Zimbabwean women.

A study of 119 lactating Zimbabwean women confirmed that progestogen-only oral contraceptives (OCs) are a safe acceptable method of postpartum fertility control. Exluton (0.5 mg of lynestrenol) was administered within six weeks of delivery and follow-up appointments were scheduled at three six nine and twelve months after initiation of OC use. No pregnancies were recorded during the 1556 study cycles. 95% of study participants reported that their milk supply remained adequate and 93% expressed satisfaction with the method. Infants of OC users demonstrated steady gains in weight and head circumference. Headache was the most commonly reported side effect but its incidence decreased from 12% in the first three months of use to 2% in the second three months. There were no significant alterations in maternal weight or blood pressure.
